Description

FIELD OF THE INVENTION

The present invention belongs to the technical field of medicament, and specifically relates to a pyrimidine derivative, its phamaceutically accepted salts, its hydrates and solvates, its polycrystalline and eutectics, its precursors and derivatives of the same biological function, and the preparation method and use thereof.

BACKGROUND ARTS

AIDS, i.e. acquired immune deficiency syndrome, is an epidemic caused by human immunodeficiency virus (HIV). During the process of HIV's reverse transcription from mRNA to DNA, reverse transcriptase (RT) performs a decisive function, and therefore becomes an important target for the design of anti-AIDS medicines.

Among the current studies of anti-HIV medicines, non-nucleoside reverse transcriptase inhibitors (NNRTIs) have become one of the hotspots in the field of pharmaceutical chemistry for the benefits of high efficiency and low toxicity and etc thereof. At present, 4 kinds of reverse transcriptase inhibitors have received FDA approval: Nevirapine, Delavirdine, Efavirenz and etravirine (TMC125). In addition, .alpha.-APA089439, HBY097 and TMC-278 are undergoing clinical studies. Classical NNRTIs are only effective against HIV-1, but ineffective against HIV-2.

Therefore, this field urgently needs a novel medicine to prevent or treat AIDS.

Anti-HIV Biological Activity Test in the Embodiments of the Present Invention

Anti-virus activity of cells in vitro was determined by Rega Institute for Medical of Spain Katholleke University, consisting mainly: inhibitory activity towards HIV-infected MT-4 cells and cell toxicity. The method is described below: exert the compound on the HIV-infected ME-4 cells, and determine the protection of the drug on the cell lesions induced by HIV at varied HIV-infection intervals, calculate the half effective concentration IC.sub.50, the required concentration that protect 50% of cells from cell lesions induced by HIV. Toxicity determination is carried out in parallel with anti-HIV activity experiments, also in the cultured MT-4 cells, determine the CC.sub.50, the concentration that leads 50% of uninfected cells to cell lesions, and calculate the selectivity index SI=CC.sub.50/IC.sub.50 with the MTT method.

Materials and Methods

Anti-HIV activity of various compounds is monitored by the inhibitory efficiency of drugs on the cell lesions induced by HIV. Carry out cell culture with MT-4 cells. The adopted virus strains are HIV-1 IIIB strain and drug-resistant viral strain of L103N+Y181C.

The detailed operation is as follows: the compound is dissolved with DMSO or water and diluted with phosphate buffer saline, 3.times.10.sup.5 MT-4 cells are cultured with 100 .mu.L various concentrations of compounds for 1 h, then 100 .mu.L suitable virus dilution is added to the compound, and the cells are cultured at 37.degree. C. for 1 h. After being washed for 3 times, the cells are suspended again in the culture media containing or not compounds individually. Subsequently, the cells are transferred to the atmosphere containing 5% CO.sub.2 and cultured for 7 days at 37.degree. C., and culture media containing or not compounds are used to replace or supplement the culture solution on the third day after infection. Kinds of culture conditions should be duplicated. The cell lesions caused by virus are monitored with reverse light microscopy everyday. Typically, the virus dilution applied in the present experiments generally cause cell lesion on the fifth day after infection. Inhibitory concentration of a drug is expressed with the concentration that is required for 50% inhibition of cell lesions (EC.sub.50) caused by virus and meanwhile shows no direct toxicity to cells (CC.sub.50). It should be emphasized that, when the compound is poorly water-soluble and can only be dissolved in DMSO, the ratio of DMSO to water is generally below 10% (the final concentration of DMSO in MT-4 cell culture media is smaller than 2%). Because DMSO can influence the anti-virus activity of the tested compounds, blank tests on the solution containing the same concentration of DMSO should be conducted in parallel. Additionally, the final concentration of DMSO is far below the concentration required to influence the replication of HIV-1 in T cells.
